Be it known that I,- Tiinononn BoNRon, a

citizen of the United States of America, re?- siding at the city of Louis, in the State ofMissouri, haveinvented certain new and useful Improvements in Ball-Cocks for Water-Closet Cisterns, of which the followingis a -full, clear, and exact description, reference being had l to the accompanying drawing, forming part "of this specification. My invention relates to a ballcock for water closetcisternsanclit has for its object the production of a'coek*iof=this description which- 1 is of simple and. efficient construction, is not liable to; become 1mpaired during service, and :by; which the waterdischarged througln the cock is directed to the bottom of the cistern ina manner to cleanse saidbottom each time that water is delivered through the coclg-l'thereby,

preventing the accumulation of sediment in the cistern.

Figure I is a vertical section taken through an overhead water closet cistern and my ball cock therein. Fig. II is a top or plan view of the ball cock. Fig. III is a cross section taken on line III-III, Fig. I. Fig. IV is in part a vertical section through a low water closet cistern and in part an elevation of a form of my ball cock suitable for use in a low cistern.

In the accompanying drawings and referring first to Figs. I to III, inclusive: A designates an overhead water closet cistern, and B a water delivery pipe leading to said cistern. 1 designates the tube of a valve housing formed in one piece and having a base collar 1 seated in the cistern A and having connection with the water delivery pipe B. This housing has arranged in its wall and within the cistern adjacent to the base collar 1 a plurality of radial ports 2 for the escape of water from the interior of the valve housing after it has risen in said housing from the delivery pipe. The housing 1 is of the same internal diameter throughout its length in order that the interior surface of the housing may serve as a valve seat. 3 is an annular downwardly flaring deflector surrounding the valve housing immediately above its radial ports and forming an annular outlet passage surrounding the base collar 1 by which the water is deflected over the base collar 1 against the bottom of the cistern A as it 1 Specification of Letters Patent.

emerges through the radial ports ythereby 'causlng the water to be forcibly driven against thebottom ofthe cistern for cleansing action. 4 designates avalve stem that is loosely fitted in the tube of the valve housing and protrudes above the upper end'of said housing. In this valve stem is a :vertical slot 5. 6 isaucup valveof the same diameter as the valve chamber 'andxof suitable material "that is attachedwtoithe loweruend of the valve stem at,preferably'bymeansof: a

screw thatpasses centrally; through the valveuandfinto the: stem. This cup :valve serves to control the radial ports 2 in the valve housing by. fitting against-the :internal valve seat surface ofthe housingat the location of saidzradialxportg iThevalve stemf l is lCOlltI'OllBd"byj float. ball 8. This. float ball is carried byi a-rod 9 that. is fitted to "a lever-E member? 10, -w'hich has. an arm, 11

loosely positioned in the slot in the valve stem 4. The lever member 10 is pivotally supported intermediate of its ends by a pivot pin 12 mounted in a suitable ear supported by and projecting laterally from the upper end of the valve housing 1.

In the practical use of my ball cook, the valve stem l and the cup valve 6, carried thereby, occupy the ositions seen in Fig. I, when a quantity of water to be used for closet flushing action is present in the cistern, at which time the cup valve serves to prevent additional inflow of water into the cistern, due to its being seated in contact with the internal surface of the valve housing at a point beneath the radial ports 2. When the water is discharged from the cistern, the float ball descends and the arm 11 of the lever member 10 by acting freely in the slot of the valve stem acts to elevate said stem and carry the cup valve gradually in an upward course with the result of permitting the flow of water through said radial ports from the lower portion of the valve housing toward the deflector and over the base collar 1 and into the cistern. The water continues to flow into the cistern to fill it and cleanse its bottom surface at the same time until the proper level of water in the cistern has been obtained, at which time the valve stem will have been again lowered under the influence of the float ball and the lever member 10 with which the valve stem cooperates.

In Fig. IV, I have shown my ball cock constructed in a manner suitable for use in a low water closet cistern. The construction of the cock in this instance differs only from the cock previously described, in that the valve housing is surmounted by a tubular extension 1 and the valve stem is connected to an extension rod 4 to the upper end of which is attached a head 46* that is slotted and receives the arm of the lever member 10. This construction provides for the float ball 8 being located at a considerably greater elevation than that at which it is located when used in an elevated cistern. 13 is an after-fill pipe leading upwardly from the valve housmg and to the upper end of the flush pipe 14.

It will be perceived that the ball cock herein described, is susceptible of free and easy action at all times and will therefore operate instantly in either direction of movement of the parts. A point to which I desire to direct particular notice, is that the cup valve 6 operates against the internal valve seat surface of the housing 1 and that consequently should the internal surface of the housing become worn away at the location of the radial ports 2, by the friction of water thereagainst, the cup valve will perform its function inasmuch as it is susceptible of moving to a considerable distance beneath the radial ports. It should also be added that if the internal valve seat surface of the valve housing becomes worn beneath the radial ports, thereby permitting water to escape past the cup, valve when it extends only slightly beneath the radial ports, the amount of water admitted to the cistern will be increased and the float will cause the valve stem to be lowered to a greater degree, whereby the admission of water to the cistern will be stopped before there has been an objectionable increase of delivery of water into the cistern.

I claim:

A ball cock comprising a housing with a tube of the same internal diameter from end to end and provided with radial ports, and with an annular downwardly flaring deflector surrounding the tube overhanging the radial orts and extending outwardly therefrom f i ee at its outer edge from adjacent parts of the cock, and a valve stem within the tube provided with a cup valve at its lower end of the same diameter as the stem and the peripheral surface of which controls the radial ports.
